Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a wire harness protector, and more particularly to a wire harness protector capable of easily adjusting the position of a clip portion which is locked in a clip hole of a vehicle body panel or the like.

[0002]

2. Description of the Related Art In order to protect a wire harness used for wiring various electric components mounted on an automobile, a protector made of a synthetic resin for housing the wire harness is used. As shown in FIG. 4 (A), in this type of protector 1, a lid 1B whose upper surface opening can be opened and closed is integrally formed on the upper part of a gutter-shaped protector body 1A whose upper surface is opened. When the wire harness W / H is housed in the protector body 1A and the lid 1B is closed, the lock hole 1a of the lid 1B is locked by the lock claw 1b of the protector body 1A, and the lid 1B is locked by the protector body 1A. It is like this.

At both ends in the length direction of the protector body 1A, tape fixing portions 1c, 1c for fixing the wire harness W / H with the adhesive tapes 2, 2 are integrally molded, respectively, and the protector body 1A is also formed. At the bottom of 1A,
A pair of clip portions 1d, 1d inserted in the clip holes 3a, 3a of the vehicle body panel 3 and locked in the length direction.
Are integrally molded.

By the way, when fixing the protector 1 to the wire harness W / H, if the grommet 4 is attached to the wire harness W / H, for example, as shown in FIG. Since the dimension L between the partition wall 5 of the vehicle body to be fixed and the clip hole 3a of the panel 3 is already determined, each tape fixing portion 1c of the protector 1 is connected to the wire harness so that the clip portion 1d matches the dimension L. It is necessary to fix it to the W / H with the adhesive tape 2.

The protector 1 is connected to the wire harness W / H.
Since the work of fixing the tape 2 to the tape 2 is often a manual work by an operator and an error is unavoidable, a predetermined tolerance (for example, about ± 5 mm) with respect to the dimension L is usually accepted. .

[0006]

However, in the case where the protector 1 is fixed to the wire harness W / H with the maximum tolerance l (+5 mm in the above tolerance example) [Fig.
(Refer to the solid line in (B)] Since the clip portion 1d of the protector 1 deviates from the clip hole 3a by the maximum tolerance l, the protector 1 is placed at a predetermined position (± 0 in the above tolerance example).
mm) forcibly in the direction of the arrow a to bend the wire harness W / H and clip the clip portion 1d to the clip hole 3
It is necessary to insert it into a and lock it. (Refer to the chain double-dashed line in the figure.) In that case, when the outer diameter of the wire harness W / H is large, the wire harness W / H is difficult to bend and there is a problem that it is very difficult to lock the protector 1. It was

As shown in FIG. 5, the tape fixing portions 6a and 6a of the clips 6 and 6 are fixed to the wire harness W / H with the adhesive tape 2, respectively, and the tape is fixed between the tape fixing portion 6a and the clip portion 6b. Although there are provided those in which the bellows portions 6c and 6c are connected (see Japanese Utility Model Laid-Open No. 63-187530), it is necessary to provide clips 6 and 6 which are separate members, and the number of parts increases and these clips are also provided. There is a drawback that the tape winding work for attaching the tape fixing portions 6a, 6a to the wire harness W / H is required, which increases the number of work steps. Further, since the clip is not provided on the protector, it cannot be immediately adopted for the protector.

The present invention has been made to solve the above-mentioned problems, and makes it possible to easily adjust the position of the clip portion provided on the protector, thereby improving the workability of engaging the clip hole of the vehicle body panel or the like. An object of the present invention is to provide a protector for a wire harness.

[0009]

In order to achieve the above object, according to claim 1 of the present invention, a protector for accommodating a wire harness has fixing portions for fixing the protector to the wire harness at both ends in the longitudinal direction. Together with a protector for a wire harness having a clip portion locked to a clip hole of a vehicle body panel or the like outside the protector,
At least one between the protector and each fixed portion,
The present invention provides a protector for a wire harness, characterized in that the protector is connected by a flexible portion that can be flexed in the length direction.

Further, according to a second aspect of the present invention, the protector for accommodating the wire harness has fixing portions for fixing to the wire harness at both ends in the longitudinal direction, and the protector is provided outside the protector with a clip hole for a vehicle body panel or the like. In a protector for a wire harness having a clip portion to be locked, the protector is divided into at least three in the length direction, and the respective divided protectors are connected by a bendable portion that is bendable in the length direction. The present invention provides a protector for a wire harness, characterized in that the clip portion is provided on a split protector at an intermediate position having no fixing portion.

The flexible portion may be curved in an arch shape. (Claim 3) Further, a plurality of the clip portions may be provided at intervals in the length direction of the protector. (Claim 4) When the two clip portions are provided, in the protector according to the second aspect, one clip portion is provided on either one of the split protectors having the fixing portion, and the other of the clip portions has the fixing portion. It is preferable that the split protector is provided at an intermediate position which is not provided. (Claim 5)

[0012]

According to the protector of claim 1 of the present invention, between the fixing portion and the protector provided at both ends of the protector,
By connecting with the flexible part that can be flexed in the length direction, only the protector can be slid in the length direction of the wire harness, and the position of the protector clip part can be easily aligned with the clip hole of the vehicle body panel etc. It can be adjusted.

As a result, the tolerance when fixing the protector to the wire harness is further relaxed, so that the workability of fixing the protector to the wire harness is improved. Further, since only the protector can be slid in the length direction of the wire harness and locked to the vehicle body panel or the like without bending the wire harness, the workability of locking to the vehicle body panel or the like is improved.
Furthermore, since the protector does not force the stress, the concentration of stress as the reaction force is reduced, and the accident such as shearing of the clip portion is eliminated.

According to the second aspect of the present invention, the protector is divided into at least three parts in the lengthwise direction, and each of the divided protectors is connected by the bendable portion which is bendable in the lengthwise direction. It is possible to easily adjust the position of the clip portion of the split protector at the intermediate position so as to match the clip hole of the vehicle body panel or the like by sliding only the chisel in the length direction of the wire harness.

According to the third aspect of the present invention, the bendability of each of the bent portions is arched to improve the formability. Further, when a plurality of clip portions according to claim 4 are provided, when the position of the clip portion from the vehicle body fixing portion is adjusted by mounting a grommet or the like, the clip portion provided with a space from the adjusted clip portion is previously set. Since it is formed so as to match the pitch of the clip holes, the clip portion can be locked in the clip holes without displacement. Further, in the case of the split protector according to claim 2, one clip part is provided on either one of the split protectors having a fixing part, and the other clip part is an intermediate position split protector having no fixing part. If provided, the clip holes provided in the panel holes can be coped with even if the pitch thereof is deviated.

[0016]

The present invention will be described in detail below with reference to the embodiments shown in the drawings. It should be noted that parts having the same configurations and functions as those of the prior art shown in FIG.

1 and 2 show a protector 8 for a wire harness according to the first embodiment. As shown in FIGS. 1 and 2,
The protector 8 has a gutter-shaped protector body 8A having an open upper surface, and a lid 8B which can be opened and closed at the upper surface is integrally molded through a hinge portion to accommodate the wire harness W / H in the protector body 8A. When the lid 8B is closed,
The lock hole 8a of the lid 8B is locked to the lock claw 8b of the protector body 8A so that the lid 8B is locked to the protector body 8A.

At both ends of the protector body 8A in the lengthwise direction, the wire harness W / H is attached to the adhesive tape 2,
The tape fixing portions 8c and 8c for fixing with 2 are integrally molded, respectively, and at the lower portion of the protector body 8A, the tape fixing portions 8c and 8c are inserted into the clip holes 3a and 3a of the vehicle body panel 3 and locked in the longitudinal direction. A pair of clip parts 8
d and 8d are integrally molded.

As shown in FIG. 2, the protector body 8 is
A and the tape fixing portions 8c and 8c are integrally connected by flexure portions 8e and 8e which are curved outward in an arch shape. Each of the flexures 8e, 8e is shown in FIG.
As shown in detail in (C), the top portion and the tape fixing portion 8c
By forming the thin hinge portions 8f and 8f at two points, the corner portions of and, as shown by two-dot chain lines b and c,
It is flexible in both lengthwise directions and is easy to bend with light force. The flexible portions 8e, 8e at both ends of the protector body 8A may be provided at only one of the ends.

When the protector 8 of the first embodiment is constructed as described above, when the protector 8 is fixed to the wire harness W / H with the adhesive tape 2, the grommet 4 is attached to the wire harness W / H. Includes a partition wall 5 of the vehicle body for fixing the grommet 4 and a clip hole 3a of the panel 3.
Since the dimension L between and is already determined, each tape fixing portion 8c of the protector 8 is fixed to the wire harness W / H with the adhesive tape 2 so as to match the dimension L. At the time of this fixing work, a predetermined tolerance (for example, ± 5 mm) with respect to the dimension L is recognized, so that the protector 8 has the maximum tolerance l (+ in the above tolerance example) for the wire harness W / H.
5 mm) (see the solid line in FIG. 1C), the clip portion 8d of the protector 8 has a clip hole 3a.
From the maximum tolerance l.

At this time, when the protector 8 is pushed to a predetermined position (± 0 mm in the above tolerance example) in the direction of the arrow a, only the protector 8 lengthens the wire harness W / H due to the bending action of the bending portions 8e, 8e. Since it slides lightly in the vertical direction (see the chain double-dashed line in the figure), the position of the clip portion 8d of the protector 8 can be easily adjusted so as to match the clip hole 3a of the panel 3, and at this adjustment position The clip portion 8d may be inserted into the clip hole 3a and locked.

Therefore, since the protector 8 can be locked to the panel 3 without bending the wire harness W / H as in the conventional case, the workability of locking the panel 3 is improved. Further, the tolerance (for example, ± 5 mm) when the protector 8 is fixed to the wire harness W / H with the adhesive tape 2 is
Because it can be more relaxed (for example ± 6 ~ 7m
m), the workability of fixing to the wire harness W / H is also improved. Furthermore, unlike the conventional case, it is not necessary to force the protector, so that the concentration of stress as a reaction force is reduced, and the accident such as shearing of the clip portion 8d is eliminated. Further, if the flexible portion 8e is curved in an arch shape, the structure is simple and the formability is good.

FIG. 3 shows a wire harness protector 9 of the second embodiment. The protector 9 includes a flat plate-shaped protector body 9A and an inverted U-shaped lid 9B integrally formed on the protector body 9A so as to be openable and closable via a hinge portion.
When the wire harness W / H is housed in A and the lid 9B is closed, the lock hole 9a of the lid 9B is locked by the lock claw 9b of the protector body 9A, and the lid 9B is locked by the protector body 9A. Has become.

At both ends in the lengthwise direction of the side portions of the protector body 9A, the adhesive tape 2 is attached to the wire harness W / H.
The tape fixing portions 9c and 9c for fixing with 2 are integrally molded, respectively, and the lower portion of the protector body 9A is inserted into the clip holes 3a and 3a of the vehicle body panel 3 and locked in the longitudinal direction. A pair of clip parts 9
d and 9d are integrally formed.

The protector 9 is divided into three parts in the lengthwise direction, and between the divided protectors 9-1, 9-2, 9-3,
, 9e, which are curved outward in an arch shape, are connected to each other. The protector 9 is
It may be divided into four or more in the length direction. Each of the flexures 9
Like the flexure portion 8e of the first embodiment, e is flexible in both lengthwise directions and is easy to flex with light force. The bending portions 9e, 9e at the left and right positions of the divided protectors 9-1, 9-2, 9-3 may be provided on only one of them. One of the pair of clip portions 9d and 9d is provided on the left or right split protector 9-1 or 9-3 having the tape fixing portion 9c (in this example, it is provided on the left split protector 9-1. ), The other of the clip portions 9d is provided on the split protector 9-2 at an intermediate position without the tape fixing portion 9c.

When the protector 9 of the second embodiment is constructed as described above, when the protector 9 is fixed to the wire harness W / H with the adhesive tape 2, the respective tapes of the protector 9 are made to match the above-mentioned dimension L. The fixing portion 9c is fixed to the wire harness W / H with the adhesive tape 2. When the clip portion 9d of the protector 9 is displaced from the clip hole 3a of the panel 3 by the maximum tolerance l, the protector 9 is pushed to a predetermined position (± 0 mm in the above tolerance example) in the arrow a or a'direction. By the bending action of the bending portions 9e, 9e, only the split protector 9-2 at the intermediate position slides lightly in the length direction of the wire harness W / H. Therefore, the position of the clip portion 9d of the protector 9 is set to the panel 3 It can be easily adjusted so as to match the clip hole 3a, and the clip portion 8d may be inserted into the clip hole 3a and locked at this adjusted position.

Therefore, as in the first embodiment, the protector 9 can be locked to the panel 3 without bending the wire harness W / H, and the workability of locking the panel 3 is improved. .

[0028]

As is apparent from the above description, since the protector for a wire harness according to claim 1 of the present invention is such that the protector and the fixed portion are connected by the flexure portion, only the protector is the wire harness. It becomes possible to easily adjust the position of the clip portion of the protector by aligning it with the clip hole of the vehicle body panel or the like by sliding it in the length direction.

Therefore, since the tolerance when fixing the protector to the wire harness is further relaxed, the workability of fixing the protector to the wire harness is improved, and the protector can be mounted on the vehicle body panel or the like without bending the wire harness. Since it can be locked, the workability of locking the vehicle body panel or the like is improved. Furthermore, since the protector is not forcedly pushed, the concentration of stress as a reaction force is reduced, and accidents such as shearing of the clip portion are eliminated.

According to the protector of claim 2 of the present invention, since the protector is divided into at least three parts in the lengthwise direction and the respective divided protectors are connected by the flexible portion, only the divided protector at the intermediate position is long. By sliding in the vertical direction, the position of the clip portion of the split protector at the intermediate position can be easily adjusted so as to match the clip hole of the vehicle body panel or the like.

By bending each of the bending portions in an arched shape as in claim 3, the shape is simple and the formability is improved. Further, when the protector is provided with two or more clip portions as in the fourth aspect, each clip portion can be aligned with the clip hole of the vehicle body panel.

When one of the plurality of clip portions is provided in the intermediate portion having no fixing portion, and the other of the clip portions is provided in the portion having the fixing portion at one end,
Even if the pitch of the clip holes on the vehicle body panel side is deviated, the pitch of the clip portion of the protector can be adjusted to match.
